Relationship Between arsenic IVBA Data for Soils Assessed Using a Variety of IVBA Methods

Assay	Phase	Relationship Parameters
		Slope	Y-intercept	r2
SBRC	Intestinal	0.42	5.00	0.36
PBET	Gastric	0.74	−2.56	0.84
	Intestinal	0.63	−0.15	0.78
IVG	Gastric	0.96	−4.90	0.90
	Intestinal	0.65	−0.95	0.80
DIN	Gastric	0.74	−0.42	0.81
	Intestinal	0.75	−0.49	0.80
UBM	Gastric	0.87	6.24	0.68
	Intestinal	0.86	5.02	0.64

Arsenic IVBA results for each methodology and phase are compared to data determined using the SBRC gastric phase.
